Therefore the fraction of detected gamma rays is 50% of this fraction
Photometry is a branch of science that deals with the measurement of electromagnetic radiation, particularly visible light, and its effects on various materials and organisms. It involves the use of instruments and techniques to accurately measure the intensity and distribution of light.
A simple photometry experiment involves using a photometer, such as a spectrophotometer or colorimeter, to measure the intensity of light transmitted through a sample. This can be used to determine the concentration of a substance in the sample, or to study the effects of light on the sample.
There are several factors that can affect the accuracy and reliability of a simple photometry experiment. These include errors in calibration of the instrument, variations in light source intensity, contamination of the sample, and human error in recording measurements.
If something goes wrong in a simple photometry experiment, the first step is to check the calibration of the instrument and ensure that the light source is stable. If the measurements are still not accurate, the sample may need to be cleaned or the experiment may need to be repeated with more precise techniques. It is also helpful to have a colleague double-check the results to ensure accuracy.
Photometry has a wide range of applications in scientific research, including chemical analysis, environmental monitoring, and biological studies. It is used to measure the concentration of substances in a sample, study the effects of light on organisms, and monitor changes in light intensity over time. It is also used in fields such as astronomy, where it is used to measure the intensity of light emitted by stars and other celestial objects.
